Product details
Overview
BC847AQBZ from Nexperia is an AEC-Q101 qualified NPN general-purpose transistor in a leadless DFN1110D-3 (SOT8015) package, rated for 45 V VCEO, 100 mA IC, and DC current gain (hFE) of 110–220 at VCE = 5 V and IC = 2 mA. It serves as a compact, high-reliability switching and amplification device in space-constrained automotive and industrial PCBs.
For engineers reviewing the BC847AQBZ datasheet, BC847AQBZ pinout, BC847AQBZ application, or BC847AQBZ equivalent, this part supports AOI-compatible solder joint inspection, operates up to 150 °C junction temperature, delivers low VCE(sat) ≤ 400 mV at IC = 100 mA / IB = 5 mA, and features side-wettable flanks for reliable reflow soldering on FR4 PCBs.
Technical Context
This transistor implements standard bipolar junction architecture with base-emitter forward bias enabling controlled collector current flow. Its design targets stable DC amplification and fast-switching behavior under low-to-moderate power conditions (Ptot ≤ 420 mW on 70 µm copper FR4).
Thermal performance is defined by Rth(j-a) = 298 K/W (70 µm copper) and transient thermal impedance curves supporting pulsed operation up to 200 mA peak. The device meets AEC-Q101 stress test requirements for automotive discrete semiconductors, including temperature cycling, HTRB, and ESD robustness.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum safe collector-emitter voltage with base open; defines upper rail limit in switching applications. |
| IC | 100 mA - Continuous DC collector current rating; sets maximum steady-state load drive capability. |
| hFE | 110–220 - DC current gain range at VCE = 5 V, IC = 2 mA; determines required base drive for target collector current. |
| VCE(sat) | ≤ 400 mV - Collector-emitter saturation voltage at IC = 100 mA, IB = 5 mA; directly impacts conduction loss and heat generation. |
| Ptot | 420 mW - Max total power dissipation on FR4 with 70 µm copper; constrains usable IC×VCE product in thermal design. |
| Tj(max) | 150 °C - Absolute maximum junction temperature; enables operation in under-hood automotive environments. |
| AEC-Q101 | Qualified - Certified for automotive use per stress test standard; validates reliability for engine control, body electronics, and ADAS subsystems. |
Pinout & Package
BC847AQBZ uses the DFN1110D-3 (SOT8015) ultra-thin leadless package: 1.1 mm × 1.0 mm × 0.48 mm body, 0.65 mm pitch, side-wettable flanks for optical solder inspection, and 0.5 mm profile height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control terminal; forward-biased to enable collector current flow; requires ~0.7 V VBE at IC = 10 mA. |
| 2 | Emitter (E) | Current return path; internally connected to package thermal pad in DFN layout; must be routed to ground plane for thermal relief. |
| 3 | Collector (C) | Output current terminal; handles full load current; electrically isolated from package backside in SOT8015 construction. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability across temperature cycling, humidity, and lifetime stress tests. |
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints without X-ray; improves manufacturing yield in high-volume SMT lines. |
| Ultra-small footprint | 1.1 mm × 1.0 mm area - reduces PCB real estate by >50% vs. conventional SOT23, critical for wearables and sensor modules. |
| Low profile (0.48 mm) | Minimizes mechanical interference in stacked or shielded assemblies; compatible with conformal coating and mechanical overmolding. |
| High thermal dissipation | Rth(j-a) = 298 K/W on 70 µm FR4 - supports higher continuous current than comparable 0.6 mm-height packages under identical board layout. |
Applications
| Automotive Body Control Module | Industrial Sensor Signal Conditioning |
|---|---|
|
Use Scenario: Driving LED status indicators and small relays in door modules and lighting controllers. IC Role / Device Role / Timing Role: NPN switch controlling 20–80 mA loads with <1 µs turn-on/turn-off delay. Use Value: AEC-Q101 qualification ensures 15-year field life; side-wettable flanks eliminate post-reflow solder void inspection bottlenecks. |
Use Scenario: Amplifying low-level analog signals (e.g., thermistor or bridge outputs) before ADC sampling. IC Role / Device Role / Timing Role: Linear amplifier operating in active region with hFE stability across –40 °C to +125 °C ambient. Use Value: Tight hFE bin (110–220) enables predictable bias network design; low VBE drift (–2 mV/K) maintains gain accuracy over temperature. |
| Portable Medical Device Power Management | Smart Home Actuator Interface |
|
Use Scenario: Enabling/disabling power rails for Bluetooth LE modules and display drivers in battery-powered monitors. IC Role / Device Role / Timing Role: Low-quiescent-current switch with ICBO ≤ 15 nA ensuring minimal standby leakage. Use Value: 420 mW Ptot allows sustained 100 mA switching without heatsinking; 0.48 mm height fits within slim enclosure constraints. |
Use Scenario: Level-shifting and driving small solenoids (e.g., smart lock latches) from 3.3 V microcontroller GPIOs. IC Role / Device Role / Timing Role: Digital interface buffer providing current gain (hFE ≥ 110) and voltage isolation between logic and actuator domains. Use Value: VCEO = 45 V safely accommodates inductive kickback from 24 V solenoids; low VCE(sat) minimizes self-heating during extended duty cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN general-purpose transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847BW,115 (Nexperia) | SOT323 package (larger footprint, no side-wettable flanks); same hFE bin and VCEO/IC ratings. | Lacks AOI support and AEC-Q101 qualification; suitable only for non-automotive consumer designs. | Select when board assembly does not require AOI or automotive qualification, and SOT323 footprint is already standardized. |
| MMBT3904LT1G (onsemi) | SOT23-3 package; hFE = 100–300 (wider spread); not AEC-Q101 qualified; VCEO = 40 V (5 V lower). | Lower voltage margin and unqualified for automotive; acceptable for cost-sensitive industrial controls with <40 V rails. | Choose for legacy SOT23 layouts where pin compatibility and lower unit cost outweigh AOI and automotive compliance needs. |
Compared with BC847BW and MMBT3904LT1G, BC847AQBZ uniquely combines AEC-Q101 certification, side-wettable flanks for AOI, and ultra-compact DFN1110D-3 packaging-making it the only option among the three qualified for next-generation automotive ECUs and space-constrained industrial sensors requiring zero-defect solder joints.

FAQ
What is the maximum allowable junction temperature for BC847AQBZ?
The absolute maximum junction temperature (Tj) is 150 °C, as specified in Table 6 of the Nexperia datasheet. This rating enables operation in under-hood automotive environments and high-ambient industrial enclosures. Thermal design must ensure that power dissipation (IC × VCE) and board-level thermal resistance keep actual Tj below this limit under worst-case conditions.
Does BC847AQBZ support automatic optical inspection (AOI) of solder joints?
Yes - BC847AQBZ features side-wettable flanks per its DFN1110D-3 (SOT8015) package definition. These exposed metal sidewalls allow standard AOI systems to verify solder fillet formation and wetting quality without requiring X-ray inspection, improving manufacturing throughput and defect detection in high-volume SMT lines.
How does the hFE range of BC847AQBZ compare to BC847BQB and BC847CQB variants?
BC847AQBZ has hFE = 110–220 at VCE = 5 V and IC = 2 mA; BC847BQB is binned 200–450; BC847CQB is 420–800. All share identical package, voltage/current ratings, and AEC-Q101 qualification - the hFE binning enables precise bias network selection for analog gain stability or digital switching threshold control.
Is BC847AQBZ pin-compatible with standard SOT23-3 transistors like MMBT3904?
No - BC847AQBZ uses the DFN1110D-3 (SOT8015) leadless package with 0.65 mm pitch and side-wettable flanks, while MMBT3904 uses SOT23-3 with gull-wing leads and 0.95 mm pitch. Physical mounting, solder stencil design, and PCB footprint are incompatible; redesign is required to substitute between these packages.
